Answers

Answer 1

The type of plot that can be used to determine λ max of a solution is Absorbance vs wavelength.

The correct option is C.

What is the plot of Absorbance vs wavelength?

The plot of absorbance vs wavelength is called an absorption spectrum or an absorbance spectrum.

In this plot, the x-axis represents the wavelength of light, usually in nanometers (nm), and the y-axis represents the absorbance of the sample at that particular wavelength. The absorbance is a measure of how much light is absorbed by the sample at a specific wavelength.

The absorption spectrum is used to identify the wavelengths at which a substance absorbs light and can be used to determine the identity or concentration of the substance. The pattern of peaks and troughs in the absorption spectrum is unique to each substance, making it a useful tool in analytical chemistry and biochemistry.

when potassium chloride is exposed to a flame, the light given off is the result of

Answers

When potassium chloride is exposed to a flame, the light given off is the result of atomic emission.

When a compound is heated, the energy is absorbed by the atoms or ions in the compound, causing them to become excited and jump to higher energy levels. As the atoms or ions return to their original energy levels, they release the excess energy in the form of light. This phenomenon is known as atomic emission.

In the case of potassium chloride, the energy absorbed by the atoms causes them to emit light in the visible spectrum, which produces a characteristic violet color. This process is commonly used in flame tests to identify the presence of specific elements or ions in a sample.

How does gravity have the potential to exert force on the girl?

Answers

Answer:

Gravity has the potential to exert force on the girl because she has stored energy due to her position, and gravity can act on this energy.

Explanation:

Gravity is a fundamental force in the universe that attracts objects with mass to one another. The force of gravity is determined by the mass of the objects and the distance between them. The girl, being a massive object, is subject to the force of gravity due to the Earth's mass. Because the girl has mass, she is also attracted to the Earth by gravity. The potential for gravity to exert a force on the girl comes from the position of the girl relative to the Earth. The closer the girl is to the Earth, the stronger the force of gravity on her. This potential energy can be converted into kinetic energy if the girl falls towards the Earth, as the force of gravity accelerates her downward.

A sample of carbon dioxide is held in a 3.00 L container at a temperature of 20.0 °C
and a pressure of 725 torr. What is the density of the carbon dioxide given these conditions? What mass of carbon dioxide is present?

Answers

Therefore, the density of the carbon dioxide at these conditions is 1.54 g/L, and the mass of carbon dioxide present is 4.61 g.

What is pressure?

Pressure is defined as the amount of force per unit area. It is a measure of how much force is distributed over a given surface area. Pressure can be represented by the symbol P and is typically measured in units such as Pascals (Pa), pounds per square inch (psi), or atmospheres (atm). Pressure is a fundamental concept in physics and is involved in a wide range of phenomena, from the behavior of fluids to the operation of mechanical devices. For example, when a force is applied to a gas, the gas molecules collide with the walls of the container and exert a pressure on the walls. This pressure is proportional to the number of gas molecules, the temperature of the gas, and the volume of the container.

Here,

To calculate the density of the carbon dioxide, we can use the ideal gas law, which relates the pressure, volume, temperature, and amount of gas to each other:

PV = nRT

where P is the pressure, V is the volume, n is the amount of gas in moles, R is the universal gas constant, and T is the temperature in Kelvin.

First, we need to convert the temperature to Kelvin by adding 273.15:

T = 20.0 °C + 273.15 = 293.15 K

Next, we can rearrange the ideal gas law to solve for the amount of gas:

n = PV/RT

We can use the given values for P, V, and T, and the value for R is 0.08206 L•atm/(mol•K), which we can convert to torr•L/(mol•K) by multiplying by 760 torr/atm:

n = (725 torr)(3.00 L)/(0.08206 L•atm/mol•K)(293.15 K) = 0.1049 mol

The molar mass of carbon dioxide is approximately 44.01 g/mol. To calculate the mass of the carbon dioxide, we can multiply the amount of gas by the molar mass:

mass = n × molar mass = 0.1049 mol × 44.01 g/mol = 4.61 g

Finally, we can calculate the density by dividing the mass by the volume:

density = mass/volume = 4.61 g/3.00 L = 1.54 g/L

Answers

LiOH is the most likely identity of the base added. Option A is correct.

The pH of 12 indicates that the solution is strongly basic. To determine the identity of the base added, we can compare the amount of base added to the volume of water and use the pKa values of the conjugate acids to estimate which base is most likely to produce a pH of 12.

LiOH: 6.94 + 16.00 + 1.01 =23.95 g/mol

NaOH: 22.99 + 16.00 + 1.01 = 40.00 g/mol

RbOH: 85.47 + 16.00 + 1.01 = 102.48 g/mol

KOH: 39.10 + 16.00 + 1.01 = 56.11 g/mol

Amount of base added = 0.02 g / molar mass

LiOH: 0.02 g / 23.95 g/mol = 0.000835 mol

NaOH: 0.02 g / 40.00 g/mol = 0.0005 mol

RbOH: 0.02 g / 102.48 g/mol = 0.000195 mol

KOH: 0.02 g / 56.11 g/mol = 0.000356 mol

Next, we can calculate the concentration of hydroxide ions (OH-) in the solution using the pH:

pH = 14 - pOH

12 = 14 - pOH

pOH = 2

[OH⁻] =[tex]10^{-pOH}[/tex] = 0.01 M

Using the concentration of hydroxide ions and the amount of base added, we can calculate the concentration of the base in the solution:

[OH⁻] = [base]

0.01 M = [base] / (83 mL / 1000) L

[base] = 0.00083 mol/L

Finally, we can compare the concentration of the base to the amount of base added and estimate which base is most likely to produce a pH of 12. The pKa values of the conjugate acids of the bases are:

LiOH: pKa = 10.76

NaOH: pKa = 14.00

RbOH: pKa = 13.62

KOH: pKa = 13.25

From the calculations, we see that the concentration of the base in the solution is highest for LiOH, which has the lowest molar mass among the options. Additionally, the pKa value of LiOH is closest to the pH of 12 obtained, which suggests that LiOH is the most likely identity of the base added.

Hence, A.  LiOH is the correct option.

The volume of the substance is approximately 10.20468 liters.

Volume is the three-dimensional area that a material occupies or that is encircled by a surface. The cubic metre is the common unit of volume in the International System of Units (SI) (m3). The litre (L) is the volume unit used in the metric system.

First, we need to convert the mass to grams since the density is given in grams per milliliter:

17.5 kg = 17,500 g

Then, we can use the formula:

Density = mass / volume

to solve for the volume:

volume = mass / density

volume = [tex]17,500 g / 1.71 g/ml[/tex]

volume = 10,204.68 ml

Finally, we can convert milliliters to liters by dividing by 1000:

Answers

The incident electron beam must have enough energy to overcome the interatomic interactions holding the atoms in place in the crystal lattice in order to produce a diffraction pattern for a surface with crystal spacing of 4.0.

The Bragg equation specifies the minimal energy needed for an electron with a de Broglie wavelength of to diffract off a crystal lattice with spacing d: We can change the equation 2d sin(n) = n to: h/p = h/square (2meV)

we discover that 2d sin() = n h / sqrt (2meV)

When we solve for V, we obtain: V = h2 / (2me * 2)

The electron's mass, m, is equal to 9.11 x 10-31 kg, and its charge, e, is equal to 1.60 x 10-19 C. By substituting these values for the given crystal spacing, d = 4.0 = 4.0 x 10-10 m, and assuming that n = 1 (the first-order diffraction peak), and = 90° (the maximum diffraction), we obtain: = 2d /
